BAFFLE-WALL FOR LOCOMOTIVE FIRE-BQXES.

Application filed June 1, 1911. Serial No. 630,582.

Be it known that I, HAnLow D.v SAVAGE, a resident of Ashland, in the county of Boyd and State of Kentucky, have invented a new and useful Improvementin Batlle Walls for Locomotive Fire-Boxes, of which the following is aA speciiicat'ion. I

This invention relatesto'bafile walls for locomotive fire boxes.

The object of the invention is to improve the arrangement of fire brick forming such battle walls to facilitate repair of tubes, reduce the cost. of 'fire brick, and for convenience of handling.

In the accompanying drawing Figure l is a longitudinal' section through a fire box provided with my improved bathe wall; Fig. 2 is a transverse section on the line 2 2, Fig. l; Fig. 3 isa plan view of the baflie, and F ig.4 is a perspective view of one of the brick.

In the drawings l represents the front wall of' the locomotive fire box provided with,a firing opening '2; 3 represents the rear wall of said fire box; '4 the top thereof, Extending between the front and rear side walls are the usual longitudinal tubes 6 for supporting-the baille wall'. The fire box is providedwit-h four andextend substantially parallel to the centrl ylongitudinal vertical plane of the fire box, at' least forv those portions of their length which .support the baille wall and' are also inclined longitudinally, as shown.

The'balile wall 74 is composed 'of three rows of brick, .to wit, a central or intermediate row 8; and two side rows 10. The brick of the two side rows 10 are standard. shaped brick preferably rectangular both in cross section and in longitudinal section and having parallel top and bottom faces, although the side edges may if desired be shaped to cause adjacent brick to overlap. The simple form of brick shown in the drawing is, however,- preferred. These brickhave flat lower faces resting directly length as to extend from the side walls 11 at least to. the center of the second tube from said side wall. The brick can be of any suitablerlcngth, or for thatmatte'r 'a single length of brick can be used 1n various types or sizes of locomotives, as 1t will make =no difference even though each Aiside .brick extends inwardly a considerable distance beyond the second tube.

The central row 8 is formed of specially shapedkbrick having flat end portions 13 which voverlap the inner ends of the side' brick, and intermediate its ends having the downwardly projecting part 14 which lies' between the ends of the side brick, and is thereby adapted to prevent lateral move: ment of the central brick as well as ofthe side brick, as will be readily apparent.4 These central brick vary in length according to the width of lire boxes, and in fitting out any re box standard brick maybe used for the side rows 10, while the brick of the central row are of such length that the depending portions 14 lit nicely between the inner ends of the side brick. This necessitates several sizes or lengths of specially shaped brick 8, but the side 'brick 10 canv be standard for-all locomotives. As a consequence it is necessary to carry in stock a much lesser number of sizes'than with sectional fire brickfor locomotive baille walls as heretofore devised, which have required special sizes or lengths of bri-cknot only for the central rovi7 but also for theside rows. The brick ofthe side rows, it will be noticed, are of standard shape and therefore can be verycheaply manufactured, and on account of. using the same sizes or lengths in practically all locomotives a large stock thereof can be cheaply carried. By reducing the special shapes to only one row. I have eliminated one of the diiiiculties with sectional brick for locomotive baffle walls, to wit, the very large number of diierent sizes and shapes whlch must'be carried in stock. for purposes of .replacement and re. pair. A comparatively small number of different' sizes of the specially shapedbrick j The rearmost or lowermost `brick` of each i row is preferably provided with a projec. tion or projections .16 adapted to contact against the rear side wall 3 of the lire box and allow for openings or spaces 17 through which flame can escape.

The baille wall described is of compara tively cheap construction and has all of the v advantages of economy and facility of replacement and repair, in case of repairs to the circulation tube, as any prior sectional brick bailie walls, andas it requires such a limited number of different shapes or sizes is much more economical as far as the stock to be carried on hand is concerned.A Y Wha-t I claim is: l. A locomotive re box comprising in combination, side plates, longitudinally inclined circulating tubes between the side plates, two side rows of brick having flatupper and lower faces, each row thereof rest-ing on two of the longitudinal tubes, and an intermediate row of brick having flat bottom faces at their ends overlapping the endsv of thebrick of the side rows and resting on the upper faces thereof and having portions extending downwardly between the ends of said side brick and adapt- .ed to abut against the ends of said side brick to prevent lateral movement of said intermediate and said side brick, the 'brick of said side rows being adapted to be used "with either flat face up.

2. A locomotive fire box comprising in combination, side plates, longitudinally inclined circulation tubes between the side plates, two rows of rectangular fiat-faced brick resting on two of said longitudinal tubes and each brick thereof extending laterally of the fire box to the side plates thereof, and an intermediate row formed of brick having flat-faced end portions, said intermediate brick being located end to end with said side brick and having their ends overlapping andresting on the upper faces of the side brick and having a port-ion between 4the ends extending downwardly between the inner ends of'the side brick and adapted to contact therewith and prevent HARLOW DOW SAVAGE.
